Narrated Umm Kurz: The Messenger of Allah ﷺ said: Two sheep which resemble each other are to be sacrificed for a boy and one for a girl. Abu Dawud said: This is a sound tradition, and the tradition narrated by Sufyan is misunderstanding.

Narrated Umm Kurz al-Kabiyyah: I heard the Messenger of Allah ﷺ say: Two resembling sheep are to be sacrificed for a boy and one for a girl. Abu Dawud said: I heard Ahmad (ibn Hanbal) say: The Arabic word mukafiAtani means equal (in age) or resembling each other.

Narrated Umm Kurz: I heard the Prophet ﷺ say: Let the birds stay in their roosts. She said: I also heard him say: Two sheep are to be sacrificed for a boy and one for a girl, but it does you no harm whether they are male or female.

Narrated Amr bin Suhaib: On his father's authority, said that his grandfather that the Messenger of Allah ﷺ was asked about the aqiqah. He replied: Allah does not like the breaking of ties (uquq), as though he disliked the name. And he said: If anyone has a child born to him and wishes to offer a sacrifice on its behalf, he may offer two resembling sheep for a boy and one for a girl. And he was asked about Fara. He replied: Fara is right. If you leave it (i. e. let it grow till it becomes a healthy camel of one year or two years, then you give it to a widow or give it in the path of Allah for using it as a riding beast, it is better than slaughtering it at the age when its meat is stuck to its hair, and you turn over your milking vessel and annoy your she-camel.
